Abstract :
The rapid development of wireless communication systems with the operating frequency around 60GHz states the question about the environmental safety and health risk of artificially induced exposures. To investigate the basic mechanisms of the potential bioelectromagnetic interactions we studied biophysical properties of artificial biological membranes exposed to low-power millimeter-wave (MMW) radiations at 60 GHz. Different radiation parameters of the exposure were investigated. Electromagnetic field and power-density distributions were calculated analytically and confirmed by measurements. Experimental results showed variations in the superficial pressure dynamics of the membranes even for very low power density values. Topographic analysis of the membranes surface by the atomic force microscopy (AFM) did not reveal any effect of the MMW radiations on the phoshpolipid domain organization in the mixed phospholipid membranes.
